to start it, I begin with a very low ammount of air and gas, otherwise I wont get any explosions.
once it starts roaring at low freq, I slowly increase the ammount of air while doing the same with the gas.
once the air and gas flow is enough, the freq will suddenly go higher (and so the noise), increase a bit the fuel flow and slowly remove the air supply, it should be running by itself now

The video helps me a bit. I tryed starting my chinese engine with and without a needle valve, but low temperatures and propane...
I used a vaporizer, so maybe removing could help...
I'll post again, when there is something to tell.

I like the Kite jumping pics. I wanted to try this as a child (25 years ago) but no kites big enough were available. I was going to make a kite from one of my mothers bed sheets but she caught me... oww!

It sounds as good as the X-Jet, but I haven't seen the numbers played on the table. For now a pile of poker chips is just sitting in the middle of the table, and nobody seems to want them. Fame and fortune just sitting there.

Apologies for misspelling your name ,Milisavljevic.
I will continue to write it in full,it keeps my brain working!.

To answer your question;well I entertain the fantasy of building a 2000kg. total mass aeroplane using a valveless p.j. for thrust.
So, the minimum thrust I'll need is about 2x 100kgf.
I suspect I'll probably need double that for safe performance.
Best be over than under-powered.
It's all theoretical ,if the licensing authorities are reading this.

Milisavljevic and Hinote,
Did you mean that you'd be publishing results in march, or just recommencing your p.j. research in March.?
I recall you promising us something very interesting from the next reiteration of your research.Thanks for the excellent work. Ray.

Whatever the original intent was, the current status of the project is on temporary hold.

The engine has been disassembled after the semi-disastrous hot shutdown of the QD and the resulting deformation. Parts are in hand for repairs.
